Abstract
The effects of microstructures on the mechanical properties of Ti-4.5Al-2Mo-1.6V-0.5Fe-0.3Si-0.03C(KS Ti-9)were systematically investigated by conducting several heat treatments for next-generation aircraft applications. The mechanical strength of as-received KS Ti-9 exhibits high anisotropy that is derived from the intense texture(T-texture)of the primary α phase. Such high anisotropy is observed in KS Ti-9 annealed at temperatures slightly below β -transus, but it is drastically decreased in KS Ti-9 subjected to an anisotropy controlling treatment. The reduction in the anisotropy for KS Ti-9 is related to the differences in the orientations of the precipitated acicular α phase.
